Why my items are soulbounded?

Hello Staff,
I want to ask you some questions. I hope you can do something with that. I played a lot on Molten. I had a DK... it doesnt matter now. After the full wipe of the characters, you gave us the ability to restore a character. I restored a DK . I bought Free Furios Glad's gear for DK. I wasnt be able to play then and to prevent another crash of your server i sent (non-soulbound) gear to my another WARRIOR character . Now i have remembered that i have the full gear for my DK in my backpack. The gear is now "souldbound" and i cant send them back from WARRIOR to DK. Both of my characters were merged from Ragnaros. Im playing on Icecrown now. Can you do something with that ? If yes that will be awesome, if not its okay too cuz the server is beautiful anyway.
Best regards,
Jakub
